IMPROVEMENT IN MACHINES FOR TEMPERING CLAY.

Specification forming part of Letters Patent No. 128,278, dated June 25,1872.

To all whom it may concern:

, Be it known that I, SAMUEL BARNES, of Rochester, in the county ofBeaver and State of Pennsylvania, have invented a new and usefulImprovement in Machine for Temperin g Clay; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to theletters of referencemarked thereon.

The nature of my invention consists in providing the kneading-chamber ofa clay-telnpering machine with removable'curved arms furnished withdetachable kneading-fingers, the curvature of the said arms and thearrangement of said fingers with relation to each other and the body ofthe kneading-chamber being such that in the operation of tempering theclay it will be gradually drawn from the sides of the chamber toward itscenter, and by reversing the motion of the said arms and fingers theclay will be carried from the cen ter of the chamber toward its sides.

To enable others skilled in the art to make and use my invention, I willproceed to describe more fully its construction and operation.

In the accompanying drawing, which forms part of my specification,Figure l is a side elevation of my improvement in machine fortemperingclay. Fig. 2 is a top view or plan of the same.

A represents the tempering-chamber, to the sides of which are securedupright timbers B, to the upper end of which is secured a crosstimber orbeam, 0. These timbers are used for supporting the bearings for theupper end of the shaft D, the lower end of which has its bearing in thebottom of the tempering-chamber A. The lower bearing of the shaft D isprotected by a guard, g, which also shields the shaft D to a point abovethe top edge of the tempering-chamber. The curved arms 6 are secured tothe piece marked f, through which the shaft passes, and which is boltedto the shaft, as indicated at w. Kneading-fingers h and k are placed inopenings in the curved arms 0, and are so arranged with relation to eachother that the fingers h will pass through the clay which passes betweenthe fingers k,

and the fingers 7a through the clay that passes between the fingers h,both series of fingers moving the clay in curved lines toward the guardg or out toward the sides of the chamber A, the outward or inward motionof the clay being dependent upon the backward or forward motion of thecurved arms 0.

By constructing a machine as hereinbefore described clay for fire-brickor common building brick will be thoroughly and evenly tempered, with asaving of time and economy of power.

The kneading-fingers h and k are detachable, as indicated by the dottedlines 3 whereby they can be readily removed for repairs in case ofaccident, which is a great consideration in machines for tempering clay.

Having thus described the nature, construction, and operation of myimprovement, what I I claim as of my invention is A machine fortempering clay, provided with detachable curved arms 0 and detachablekneading-fingers h and k, constructed, arranged, and operating as hereindescribed.

SAMUEL BARNES.
